WATER FILTER BOWL Filed 001, .23, 1945 I lice/7122' c/Z/m/ C]: Mb/a/ak Patented Jan. 11, 1949 UNITED STATE 4 OFFICE 1 Claim.

The device forming the subject matter of this application is adapted to be employed for filtering Water and is to be used primarily but not exclusively in connection with a toilet water box.

The main object of the invention is the provision of a device which may be installed in a conventional toilet water box and which filters the water admitted by the float valve of the inlet pipe and which may be cleaned quickly and easily.

Another object of the invention is the provision of a device of the class described and of simple, durable and economical construction.

With these and other objects in view the invention resides in the novelty of construction, combination and arrangement of parts hereinafter specifically described and particularly pointed out in the appended claims.

The description should be read in connection with the accompanying drawing in which- Figure 1 is a vertical section through the preferred embodiment of my invention.

Figure 2 is a modified form.

In the drawing, in which like characters of reference designate like or similar parts, 2 denotes generally a conventional toilet water box including a bottom 3 which is apertured for the insertion of an inlet water pipe 4 held in a predetermined position by a pair of nuts 5 and conducting the water upwardly to a valve mechanism I. The same includes a valve stem 9 apertured at its upper end for the insertion of a one arm lever II] which is fulcrumed upon a pin II supported by a bifurcated portion of the valve housing. The opposite end of this lever is pivoted by a pin l2 to a link l3 which is pivotally connected by a similar pin I2 to the free end of the shorter arm of a lever l5 fulcrumed in a bracket l6 by a pin II. The bracket is part of the valve housing. The free end of the other longer arm of lever l 5 carries a float (not shown) so that the valve is opened to admit water to the box when the former falls below a predetermined level.

The valve is connected by a bent pipe 1''! to a union I 8 which may be quickly and easily unscrewed for a purpose which will become obvious as the description proceeds. The union is connected to a downwardly bent pipe which passes through a cover 22 with an interiorly threaded cylindrical flange 23 threaded upon the exteriorly threaded neck 25 of a glass bowl 26. To the lower side of the cover is secured a downwardly extending cylindrical filter support 28, the lower end of which supports a conical filter 30. The vertical portion of pipe 23 passes through the apex of the inverted filter cone and is provided below the same with an opening 32. Between the same and the apex of the cone is a washer 33 surrounding the pipe and supporting the screen.

Through the cover extends also the lower open end portion of a pipe 34 which is bent to the right and then downwardly and is open at the lower end.

To the pipe 34 is connected a downwardly bent pipe 36, the right-hand lower end of which is connected to or empties into a vertical pipe 31. The same is connected at its lower end to a valve having a housing 40 and a valve body 4| which may be lifted by an operating member 42 so that the water is conducted through the conduit 43 for flushing the toilet bowl (not shown). The

conduit 43 extends through the bottom of the water box and carries a flange 44 beneath such bottom and is connected at its upper end to the valve housing 40.

In the modification illustrated in Figure 2 the pipe ii is threaded into a conduit 19 formed in a casting 22 carrying at its outer edge a downwardly extending interiorly threaded flange 23 which is screwed upon the open exteriorly threaded neck 25 of the glass bowl 2B. A pipe 20 is threaded with its upper end into a central hole in the casting and communicates with the conduit. The lower end portion of said pipe below the washer 33 has an opening 32 and is enlarged to support the same and the filter 30.

The cover casting is further provided with a conduit 2i which opens at its inner end into the bowl and threaded at its outer end for connection to a pipe 34, having a branch 36.

The water flows through the float valve if the level of the water in the box is low enough and throughthe pipe 20 and opening 32 into the glass bowl. The impurities in the water which have a specific weight greater than the latter drop to the bottom of the bowl and may be removed by periodically disconnecting the union and unscrewing the cover from the bowl. The impurities of a specific weight less than that of water are caught by the screen so that water free from impurities flows through pipes 36, 31, valve 40 into the toilet bowl.

Water screened from sand and dirt flows through pipe 34 into the box.

I do not wish to be understood as limiting myself to the specific construction, arrangement, shape, material, spacing, design or proportions of the example of my invention illustrated and described, as it will be obvious that equivalents may be substituted and many changes made therein within the scope of the appended claim without departure from the spirit of this invention.

What I claim as novel and desire to protect by Letters Patent of the United States is as follows:

A liquid filtering device for use with flush tanks or the like, comprising a bowl for receiving the liquid and being open at one end, a cover detachably mounted upon the open end of the bowl, 2. central inlet pipe connected with the cover and extending therethrough and into the bowl and open at its bottom end, the open bottom end of the inlet pipe being spaced from the bottom of the bowl, the inlet pipe being provided near its bottom end with a shoulder, washer surrounding the inlet pipe and engaging the shoulder to be supported thereby, an upwardly flaring conical foraminous filter surrounding the pipe and having its lower end seated upon the washer, a cylindrical sleeve arranged between the cover and foraminous filter and contacting the upper end of the filter to steady the filter, and an outlet pipe extending through the cover and communicating with the interior of the sleeve.
